Detail solution

  1. The derivative of a constant times a function is the constant times the derivative of the function.

    1. Let .

    2. The derivative of is .

    3. Then, apply the chain rule. Multiply by :

      1. Differentiate term by term:

        1. The derivative of a constant times a function is the constant times the derivative of the function.

          1. Apply the power rule: goes to

          So, the result is:

        2. The derivative of the constant is zero.

        The result is:

      The result of the chain rule is:

    So, the result is:

  2. Now simplify:

The answer is:

The first derivative [src] 
       3        
----------------
(3*x - 7)*log(5)
$$\frac{3}{\left(3 x - 7\right) \log{\left(5 \right)}}$$
Simplify
The second derivative [src] 
       -9         
------------------
          2       
(-7 + 3*x) *log(5)
$$- \frac{9}{\left(3 x - 7\right)^{2} \log{\left(5 \right)}}$$
Simplify
The third derivative [src] 
        54        
------------------
          3       
(-7 + 3*x) *log(5)
$$\frac{54}{\left(3 x - 7\right)^{3} \log{\left(5 \right)}}$$
Simplify
3-я производная [src] 
        54        
------------------
          3       
(-7 + 3*x) *log(5)
$$\frac{54}{\left(3 x - 7\right)^{3} \log{\left(5 \right)}}$$
Simplify
